A: This system can be ordered through the press manufacturer on a new machine or purchased as a
retrofit to an existing press.
Q: On what Offset press types can this unit be installed?
A: The H&B LithoCoat system has been installed on most popular machine types, including: Komori,
Mitsubishi, Heidelberg, MAN Roland, KBA Planeta, Sakurai, and others.
FAQ’s
Q: I have an add-on blanket coater, can this be converted to the LithoCoat technology?
A: In most cases an existing blanket coater can be converted to include a ceramic anilox roll and the
chambered doctor blade system. Improvements in performance along with faster clean-ups and less
slinging can be expected.
Q: What is an anilox roll?
A: The anilox roll is simply a metering roll designed to consistently supply a uniform and measurable
volume of liquid. Using a computer-controlled laser, millions of microscopic holes (or cells) are vaporized
into the surface of the ceramic coating of the anilox roll. These cells are what actually cups and carries
the coating to the blanket or plate cylinder.
Q: What rolls are removed and how is the new anilox driven?
A: The smooth chrome or rubber application roll presently in the press is removed and replaced with
anilox roll of exactly the same physical dimensions. Depending on press type, split cap journals are
installed to speed future roll changes. The existing press drive is re-used to maintain an exact surface
speed match between the new anilox roll and the blanket cylinder. All of the other transfer rolls in the
coater are removed.
Q: Can I run with just one anilox roll or do I need to change rolls with every coating?
A: A typical printer will usually require one roll that can be run with all of their coatings. However, if
major variances in coating weight are required (example: switching from a flood work and turn to a
blister coating) an additional roll with a different engraving may be required. A spare roll is also smart to
have on hand.
Q: I hear of steel, aluminum, carbon fiber, chrome & ceramic anilox rolls. What’s the best choice?
A: The core of the anilox roll can be made of steel or lighter-weight aluminum and carbon fiber. The
downside to carbon fiber is a higher cost. Aluminum is half the cost of carbon fiber, can be re-engraved
more times than carbon fiber, and is still light enough to be lifted without a hoist. All cores are ceramic
coated and then laser engraved to exact specifications for the application. Mechanically engraved
chrome rolls were used in the past, but industry experts agree that ceramic offers superior performance,
accuracy and wear resistance. H&B only uses ceramic surface rolls.
Q: How do I determine the proper anilox volume?
A: As part of the complete package, H&B guarantees to supply the proper anilox roll for the application.
We also offer the use of banded rolls (rolls with different volumes) to help in testing and ultimately
deciding what the exact engraving should be.
